BC548_J35Z

Single Bipolar Transistors Overview

The BC548_J35Z is an NPN epitaxial silicon bipolar junction transistor manufactured by onsemi. It is designed for general-purpose switching and amplification applications in electronic circuits. The device utilizes a planar design and is housed in a TO-92 through-hole package with three pins. Key electrical characteristics include a maximum collector-emitter voltage of 30V, a continuous collector current rating of 100mA, and a total power dissipation capability of 500mW. The component supports a transition frequency of 300MHz and operates within a junction temperature range up to 150°C.

Single Bipolar Transistors Feature Summary

• Epitaxial silicon planar construction for reliable signal processing

• Lead-free packaging compliant with environmental directives

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Electronic switching applications
• Signal conditioning stages

Single Bipolar Transistors Procurement Notes

Verify the specific suffix J35Z against official onsemi documentation to confirm pinout orientation and marking codes. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor databases to confirm authenticity and traceability before finalizing orders.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN small-signal transistor with 30V breakdown and 100mA current capacity is required. Consider the BC548C variant if higher DC current gain is necessary for specific amplification requirements. Verify that the TO-92 package dimensions fit the target PCB layout constraints.

Single Bipolar Transistors Part Context

This component belongs to the widely used BC546/BC547/BC548 family of NPN transistors. These devices are industry-standard replacements for older general-purpose transistors. The BC548 specifically offers a 30V rating, distinguishing it from the higher-voltage BC547 (45V) and BC546 (65V) variants within the same product line.

Single Bipolar Transistors Replacement Considerations

Direct functional equivalents include the BC548B and BC548A variants from onsemi or other manufacturers. Cross-manufacturer alternatives such as those from Diotec or Fairchild may be suitable if pinouts and electrical ratings match exactly.
